[linux-audio-user] Is everyone sick of interrupts yet?

[brad stafford]

I just tonight switched from the Planet CCRMA RH9 to FC1. The install
was purely from the CDROMs dated 4/25/2004.

I've seen all the latest posts about interrupts and did the required
reading on the internet. I really managed to get RH9 cleaned up but in
FC1 I'm seeing something a little different. I have a Delta 1010 and I'm
running an AMD Barton 2.6 with 5 PCI slots. The question is what the
heck are IRQ 16 and 22? I moved the sound and ethernet cards around to
get them to 16 and 22 as they used to be eth0 on 21 and ICE1712 on 22. I
have ACPI turned off as a service but don't have a "disable" option in
the BIOS. I did turn off USB support in the BIOS.

Is 16 like the equivalent of IRQ 3 since it's following 15?

I'm getting 5.8 msec latency in JACK with 128 frames/period at 44100 and
2 periods/buffer. A huge improvement over the 46.1 msec using RH9 with
capabilities.

Thanks, Brad.
